History

Etymology

See Plutonic.

From pluton(ium) + -ic.

From Ancient Greek Πλούτων (Ploútōn, “Pluto, Greek and Roman god of the underworld”) (from πλοῦτος (ploûtos, “riches, wealth”) (ultimately from Proto-Indo-European *plew- (“to fly; to flow; to run”)) + -ων (-ōn)) + -ic (suffix forming adjectives meaning ‘of or pertaining to’). The English word is cognate with Middle French plutonique (modern French plutonique (“of or pertaining to Pluto, the underworld, or the interior of the Earth”)).
